For the question above, Ubuntu comes without SSH support. You must first install Openssh-server before anyone will be able to sign in using that protocol. For many, you probably already know what SSH is and for the few out there who don’t know, it’s a secure way to connect to another networked device.

Prior to SSH the most popular method used to connect to remote machines was Telnet. Telnet while good in those days was very insecure. All your communications back and forth were done in clear text so anyone with the right tool could intercept the traffic and read everything that were communicated.

Secure Shell was introduced as a replacement for Telnet. It’s more secure and reliable and all communications are done using encryptions.

This brief tutorial is going to show you how to enable SSH in Ubuntu 12.10.

To get started, press Ctrl – Alt – T on your keyboard to open the terminal When it opens, run the commands below to install openssh-server.

sudo apt-get install openssh-server




That’s how you enable SSH in Ubuntu. Now it’s installed, by default all communications are done using port 22. To change it to a different port number or edit the configuration to suite your needs, open the file below by running the commands.

gksu gedit /etc/ssh/sshd_config




When the file opens, make your change and save.




Many of the changes are not to be changed. If you don’t know mush about it, it’s recommended that you leave it alone.


To connect to the SSH server, use any tool that supports SSH Protocol. One popular one is Putty, download it and connect to the server using the post number you configured.
